Common problems often require common solutions and the need for a dialogue. This is true in the case of China and India when it comes to tackling air pollution and switching to clean energy.

Poor air quality has become a major political concern in both countries. It was a headline topic at the opening of the National People’s Congress in March, with China’s Prime Minister Li Keqiang reaffirming the government’s commitment to clearing the skies through increased investment in clean energy and implementing tougher sanctions for polluters.

In order to effectively tackle the pollution crises, technologies that support clean air, water and soil in both China and India must gradually replace polluting alternatives. Implementation of this transition will largely depend on local factors. So what is the best approach for each government to take in promoting these technologies: the stick or the carrot? And which incentives or disincentives are most effective?

Both countries face similar challenges. Each has prioritised the installation of de-sulfurizing, de-nitrating and de-dusting equipment at existing coal-fired electricity plants to curb harmful emissions. Both China and India have applied emissions standards to their electricity, transport and industrial sectors. However, compliance with these standards remains a major challenge. Beijing, for instance, is still believed to be at least a decade away from blue skies, whereas India lags behind further still.

To complement command-and-control regulations such as emission standards, “the stick”, China is also using a “carrot” by offering a premium sale price to coal-fired generators that have installed emissions abatement equipment. The value of this “carrot” was estimated at around 100 billion yuan per annum (US$14.5 billion) in 2014 and 2015.

Given its lower level of economic development and budgetary constraints, India cannot afford to encourage a reduction of pollution from coal plants in the same way. India prioritises provision of affordable electricity to its population and improving energy access for the 20% of people that still do not have electricity in their homes. This is very different from China, a country with an electrification rate of 100% that is addressing a major challenge of over-capacity in coal-fired generation.

India also has the cess charge (a form of carbon tax) on coal use that is partially allocated to support clean technologies. Charged at INR400 (US$6) per tonne of coal, the cess has seen an eightfold increase since 2014. Between 2011 and 2016 an estimated 13,616 crore (over US$2 billion) from the coal cess revenues was transferred to the National Clean Energy Fund.

Among its causes are “toxic carrots” given each government. In China, energy policy is conflicting. While some policies seek to curb coal capacity, others guarantee coal-fired power plants a certain number of hours of operation. Thus, the value of wind curtailment in Liaoning, Jilin, Heilongiang and East Inner Mongolia was estimated at 6.9 billion yuan (US$1 billion) in 2016 driven partly by the priority given to the use of coal power.

These and other examples illustrate that there is a lot of money and also regulations already on the table. What is missing is a system that traces the efficacy of both carrot and stick policies on energy waste and air quality in a way that is simple for governments and other stakeholders to use.

Given increasing budgetary pressures, identifying, quantifying and evaluating policies that assist or interfere with the clean energy transition could help China and India assess the best use of public resources.

One way of doing so would be a voluntary peer review with an expert organisation or another country – bilaterally or within such forums as G20 or BRICS. For example, many members of the organisation of the Asia-Pacific Cooperation have undertaken voluntary peer reviews on energy efficiency.

Another opportunity is the voluntary review of fossil fuel subsidies within the G20 that China completed jointly with the US when it was hosting the G20 summit in 2016. The purpose of this review was to identify "toxic carrots" – those measures of government support in the energy sector that result in wasteful consumption of energy. China’s review listed nine subsidies worth US$14.5 billion and included a timeline for their phase-out. India will host the G20 summit in 2019 and as more G20 countries (Germany, Mexico and Indonesia at the time of writing) volunteer for peer review, there are increasing expectations on India to do the same.
